WYNNEWOOD, Okla. — State agents seized thousands of marijuana plants and detained multiple individuals during a search warrant operation targeting illegal trafficking activity in southern Oklahoma.

On April 21, 2026, agents with the Oklahoma Bureau of Narcotics Marijuana Enforcement Teams (OBN MET) executed a search warrant at Huang Zhewei 5858 LLC in Wynnewood as part of an ongoing black-market marijuana investigation.

Authorities said agents seized 8,897 marijuana plants at the site.

Three individuals were detained during the operation, and one person was taken into custody by federal immigration authorities. Officials said additional arrests are expected as the investigation continues.

Agents with the Oklahoma Department of Agriculture also executed a separate search warrant at the location, seizing illegal pesticides discovered on the property.

The operation involved multiple agencies, including Homeland Security Investigations, U.S. Immigration and Customs Enforcement, the Oklahoma Department of Agriculture, Oklahoma Highway Patrol, the Garvin County Sheriff’s Office and the Garvin County Commissioners Office.

According to OBN, its Marijuana Enforcement Teams were created in 2021 to address the growing presence of criminal organizations operating illegal marijuana grow operations in the state, often tied to black-market distribution and fraudulent licensing schemes.

Authorities said the number of active licensed marijuana grow operations in Oklahoma has dropped significantly, from about 8,400 in 2022 to fewer than 1,400 currently.

Since 2022, OBN MET agents have seized more than 2.1 million illegal marijuana plants, over 250,000 pounds of processed marijuana and made more than 400 arrests, with additional cases still under investigation.

Anyone with information about drug or human trafficking activity can contact the OBN tip line at 800-522-8031 or submit tips through the agency’s social media channels.
